PAUL DE OHAMBERET, OF PARIS, FRANCE.

MACHINE FOR WORKING SKINS AND LEATHER.

SPECIFICATION forming part of Letters Patent No. 248,290, dated October 18, 1881. Application filed August15, 1881. (NomodeL) Patented in France January 25,1881.

To all whom it may concern Be it known that I, PAUL DE CHAMBERET, of Paris, France, have invented an Improved Machine for Shaving, Paring, Striking-Out,

and otherwise Working Skins and Leather; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed sheet of drawings, making part of the same, and that I have received French Letters Patent for fifteen years for said invention, dated January 25, 1881.

This invention rela es toa new machine for shaving and paring all kinds of skins to a regularthickness throughout. With theaid of this machine the operation of shaving skins is rendercd so easy that even a woman or child may perform it without fatigue, either sitting or standing.

In order that the invention maybe more readily understood, I have illustrated an example thereof in the accompanying drawings, in which Figurel represents a front view of the machine, and Fig. 2 a vertical central section of the same. Fig. 3 is a view of the driving end of the machine.

The machine is furnished with two knives, a I), curved to an arc of a circle, and fixed on a horizontal shaft, 0, as clearly shown in Fig. 2. A little in front of and in the periphery with the cutting-edge of each knife is a roller, 61, which smooths the skin by rolling over its surface. These rollers (Z are journaled in the ends of arms f fixed on collars 6 upon shaft 0.

The skin to be operated on is placed on a marble support, 9, which may be approached toward the knives or withdrawn by a screw, h,with squared head, said support beingmounted upon a wood cross-head, 1;, having guiderods k, which slidein cross-bars 1, serving like tie-rod m to brace the two side frames of the machine together. Upon the top bar of the machine, above the cuttters, is placed a sharpening-plate, n, which may be moved toward the knives by a screw, 0. The sharpening of the cutters is thus readily effected, and can be performed without stopping the machine.

Rotary motion is impartedto the knife-shaft by pulleyspp, and a horizontal motion is also imparted to the knives by meansof camsq upon shaft cin contact with friction-rollers "r mounted on the side frames, this movement resembling the oblique motion of the knife in the operation of shaving by hand.

The machine may either be driven by power, as shown, or by hand.

The arrangement and action of the knives may be modified according to the purpose for which they are employed.

1 claim- 1. In a machine for shaving, striking out, and paring skins and leather, a tool composed of one or more knives, a, and smoothing-rollers d, both fixed upon a horizontal shaft, 0, in combination with a vertically-movable support, 9, upon which the skin to be treated is placed, substantially as and for the purposes set forth.

2. The combination of the shaft 0 with the knife or knives a, roller or rollers d, cams q, friction-rollers r, and with the bed 9, substantially as herein shown and described.
